Is this okay to tell him I like him?

okay so i don't want to start anything but I just need to get this out because it's been bothering me! But last night when you was talking about dating other girls it made me extremely jealous & that doesn't happen with me! & i think it made me realise I actually like you a lot. And I was pissed at you & at myself because I know you just see me as the 'girl you have fun with
